In code, it's probably impractical to call it Windows 9 as that title is also part of the names of Windows 95 and 98.

Some legacy apps still using 9 as an operator in their version checking is one theory, but there are a few others as well.

Why is it called Windows 10 and not Windows 9? | ExtremeTech

my husband upgraded our 4-year-old home pc to windows 10 TP version, ah... not so good! maybe we should change a more powerful one...

^its not available yet. At least not for me.

Got the little "Windows 10 soon" notification when I got home today. I'm just about sick of 8 and accidentally finding myself back at the useless Start Screen every time my fingers slip on the keyboard, could use a change up. I'll be buying a gaming computer in October or November anyway for Fallout 4, if it'll make that a more enjoyable experience I'll gladly accept it.

Still fucking waiting on mine...

Says the 29th for me.

Same for me.

windows 10 :)

I'm honestly at a loss as to why I haven't been able to reserve my copy, my copy of Windows 7 is genuine and I've kept everything up to date. I mean I would probably still want to wait a month or so and let everyone else be a guinea pig, but to not even be asked...
